A Set of Possible Requirements for a Future Routing Architecture
Abstract
The requirements for routing architectures described in this document
were produced by two sub-groups under the IRTF Routing Research Group
(RRG) in 2001, with some editorial updates up to 2006. The two sub-
groups worked independently, and the resulting requirements represent
two separate views of the problem and of what is required to fix the
problem. This document may usefully serve as part of the recommended
reading for anyone who works on routing architecture designs for the
Internet in the future.
The document is published with the support of the IRTF RRG as a
record of the work completed at that time, but with the understanding
that it does not necessarily represent either the latest technical
understanding or the technical consensus of the research group at the
date of publication.
Status of This Memo
This document is not an Internet Standards Track specification; it is
published for the historical record.
This document defines a Historic Document for the Internet community.
This document is a product of the Internet Research Task Force
